Polymorph engineering in ErMnO3 enables low‐voltage, forming‐free threshold switching with tunable negative differential resistance. Conducting orthorhombic regions embedded in an insulating hexagonal matrix provide controlled Joule‐heating‐enhanced Poole–Frenkel transport. The hexagonal phase prevents excessive heating and breakdown.

Operando magnetic spectroscopy provides insight into how intrinsic magnetic order modulates the oxygen evolution reaction on La0.67Sr${\rm La}_{0.67}{\rm Sr}$0.33MnO$_{0.33}{\rm MnO}$3$_3$ thin films. Temperature‐dependent operando FMR and ambient‐pressure XMCD suggest a correlation between activity and the emergence of ferromagnetic regions near and ...

Electronically soft phases in manganites [PDF]
The phenomenon of colossal magnetoresistance in manganites is generally agreed to be a result of competition between crystal phases with different electronic, magnetic and structural order; a competition which can be strong enough to cause phase separation between metallic ferromagnetic and insulating charge-modulated states.

Oxygen Vacancies Driven Photoconductivity in Layered Cobaltite Epitaxial Films
ABSTRACT Understanding photoinduced phenomena in complex oxides is crucial for developing next‐generation optoelectronic devices. Here, we report pronounced ultraviolet (UV) light‐induced photoconductivity in epitaxial PrBa1‐xCaxCo2O5+δ (x = 0.5) thin films grown on (001) LSAT substrates via pulsed laser deposition.
